Unreal Engine 4.9 Released!

[DamirH]

Is anyone else having issues with texture streaming? I often have textures streaming in and everything is popping in and out of very low-res mode.

I'm sorry to repeat it, but I really want to move 4.8 project to 4.9 mainly because of AO mask. If solution isn't obvious, how can I check what's happening at 98%? Any log files? The duplicated project folder doesn't have any logs (project folder > Saved > Logs, no such folder).

Hi tonpix,

Try verifying your engine build by going to the launcher>library>4.9 context menu>verify. If this does not fix your error, please report this to the answerhub in the bug reports section (link in signature). In the answerhub report, please include your dxdiag, steps taken, and if you are able to open a clean, blank project from 4.9 or if no projects will open at all.

I'm having difficulties with convertin 4.8 project to 4.9. I opened it as copy in 4.9, but it hangs at 98%, engine stops responding according to Task Manager and it's like that for 5-10mins before I do ctrl-alt-del. It's really simple project, small landscape with trees and BP for walking character. Any suggestions? Any way to debug/read logs?

This looks like the navmesh preview, try pressing "P" to disable it

OK, i feel stupid now... that was it

This is interesting. Updating my project made my terrain fluorescent. Only shows this way in the editor and not during play.

Guys... When updating projects to new major release, remember to delete Binary folders and Intermediate folders, to have a fresh build of the project copy.
Many of the issues some report may be because you simply didn't delete these folders before upgrading.

I am quite sure UE4 is doing this automatically, where should I manually do it? The common way to update a project is to start the new version, open the old project and select "create copy". Then UE4 creates the copy and automatically starts the project - do you think I should then close the project, delete the binary and intermediate folder, and reopen it? It's always compiling all the shaders again after it's updated to a new version, so I think this means it has deleted the binary and intermediate folders.

Useful information. Is there a documentation page that lists what should be done before upgrading a project? (aside from backing up)

oO linux dedicated server -- initial observations: memory usage for our game dropped by about 30% with this version!! Woohoo!

I am getting frequent crashes selecting multiple parameter nodes in the material editor (Assertion failed IsValid()). Beware, don't try to ctrl+click on parameters. For what it's worth I was clicking on scalar and vector parameters in no particular order.

Just found another bug which is probably related to the parent issue but I just applied a Material to a base class and it reset all materials for any parents that are based off of that child BP... Okay.... this is bad Epic. Thankfully, I'll just keep my other game in 4.8.3 in the meantime but this is going to waste a lot of time if I have to go back and fix the parent class materials every time I need to change the base one.

EDIT: I just tested it a second time and same thing. This is extremely upsetting...

Here is another bug...

Deleted an asset, created a new one... attempted to undo then the editor crashed at the following line of code...

Transactor.h
FArchive& operator<<( class UObject*& Res ) override
{
int32 ObjectIndex = 0;
(FArchive&)*this << ObjectIndex;
Res = ReferencedObjects[ObjectIndex].GetObject();
return *this;
}

EDIT: For further details, ObjectIndex is 65537 but the size of the ReferencedObjects array is 2

4 or 5 people now have this problem just in this thread. I think bug fixes need to be #1 priority before pushing this stuff out. I can't make a complete vr game when every release I have to deal with issues like this over and over again. Can't use old versions because we are forced to keep updating for continual vr support....

I have this issue too,please fix that,it's a bit annoying...
